Description

Loads a Limit Line Test file and displays the test. Up to 64 Limit Line Tests can be simultaneously displayed. To specify the name of the Limit Line Test file to load, use the :LLINe:LOAD:FNAMe command. To select the waveform on which to assign the Limit Line Test, use the :LLINe:SOURce command. To apply horizontal offset to all limit lines that are defined in a displayed Limit Line Test, use the :LLINe:HOFFset command.

After the test has loaded and displayed, use the following commands to return measurement data:

For the entire Limit Line Test:

:MEASure:LLINe:FPOints? returns the number of displayed failed data points.
:MEASure:LLINe:MARGin? returns the pass/fail margin.
:MEASure:LLINe:MLOCation? returns the time location of the pass/fail margin.

For a selected limit line in the Limit Line Test:

:MEASure:LLINe:LINE:FPOints? returns the number of displayed failed data points.
:MEASure:LLINe:LINE:MARGin? returns the pass/fail margin.
:MEASure:LLINe:LINE:MLOCation? returns the time location of the pass/fail margin.
